Benign paroxysmal positional vertigo (BPPV) is one of the most common disorders that causes dizziness. The incidence of horizontal semicircular canal (HSC) BPPV ranges from 5% to 40.5% of the total number of BPPV cases diagnosed. Several studies have focused on establishing methods to treat BPPV caused by the apogeotropic variant of the HSC, namely, the Appiani maneuver (App). In 2016, a new maneuver was proposed: the Zuma e Maia maneuver (ZeM), based on inertia and gravity. The aim of this study is to analyze the efficacy of App versus ZeM in the resolution of episodes of BPPV produced by an affectation of the horizontal semicircular canal with apogeotropic nystagmus (Apo-HSC). A retrospective, quasi-experimental study was conducted. Patients attended in office (November 2014–February 2019) at a third-level hospital and underwent a vestibular otoneurology assessment. Those who were diagnosed with Apo-HSC, treated with App or ZeM, were included. To consider the efficacy of the maneuvers, the presence of symptoms and/or nystagmus at the first follow up was studied. Patients classified as “A” were those with no symptoms, no nystagmus; “A/N+”: no symptoms, nystagmus present during supine roll test; “S”: symptoms present. Previous history of BPPV and/or otic pathology and calcium levels were also compiled. From the 54 patients included, 74% were women. The average age was 69. Mean follow-up: 52.51 days. In those patients without previous history of BPPV (n = 35), the probability of being group “A” was 63% and 56% (p = 0.687) when treated with App and ZeM, respectively, while being “A/N+” was 79% and 87% for App and ZeM (p = 0.508). Of the 19 patients who had previous history of BPPV, 13% and 64% were group “A” when treated with App and ZeM (p = 0.043), and 25% and 82% were “A/N+” after App and ZeM, respectively (p = 0.021). In conclusion, for HSC cupulolithiasis, ZeM is more effective than App in those cases in which there is a history of previous episodes of BPPV (“A”: 64% (p = 0.043); “A/N+”: 82% (p = 0.021)).
Background: Muscle Tension Dysphonia is a relatively new clinical entity that, despite being one of the most frequent causes of functional dysphonia, is little-known by many otorhinolaryngologists. Objective: The objective of the current work is to describe the evolution of Muscle Tension Dysphonia—the concepts and the ways it has been diagnosed and treated—from its first descriptions to our current knowledge. Design: A scoping review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. A search of three bibliographic databases was performed to identify original articles on Muscle Tension Dysphonia. Study selection and characterization was conducted by three independent reviewers and was further reviewed by a fourth individual. In case of relocating any of the studies, it was performed by agreement of two reviewers. We excluded articles not written in English or Spanish, letters to the editor, review articles, studies of the pediatric population, articles related to dysphagia, and other publications that were not relevant. Results: The search identified 1144 articles published from 1983 to December 2022. A total of 581 studies were repeated and another 462 were excluded because they were not written in English or Spanish, were not original articles, or were not relevant to the objective of the study. Finally, 101 articles were included in the review. The articles included in the review were divided into three groups considering the objective and conclusions of each study: 21 articles were classified as “Etiology and Physiopathology”, 29 articles as “Diagnosis”, and 51 articles were included in the “Treatment” group. Conclusions: The concept of Muscle Tension Dysphonia has been developed during the last forty years. For its diagnosis, endoscopic visualization of the larynx is crucial, but must be combined with the patient’s clinical history and other methods can also be useful. This entity should be addressed in a multidisciplinary approach, with the active participation of speech therapists. Most therapeutic options include voice education, vocal hygiene, and rehabilitation of the voice.
Background: Age-related hearing loss (ARHL) is a complex communication disorder that affects the cochlea and central auditory pathway. The goal of this study is to characterize this type of hearing loss and to identify non-invasive, inexpensive, and quick tests to detect ARHL among elderly adults, seeking to preserve quality of life and reduce the burden on healthcare systems. Methods: An observational, prospective study is conducted with >55-year-old subjects divided into the following groups: normal range (Group A), detected but not treated (Group B), and detected and treated (Group C). During follow-up, Speech Spatial Qualities (SSQ12), and Hearing Handicap Inventory in the Elderly Screening test (HHIE-S) questionnaires were assessed, along with hearing levels (hearing thresholds at 4 kHz were studied in more depth), and a series of tests and questionnaires to assess balance, cognitive level, level of dependence, and depression. Results: A total of 710 patients were included in this study. The duration of hearing loss (11.8 yr. in Group B and 21.0 yr. in Group C) and average time-to-treatment for Group C (14.1 yr.) are both protracted. Both of the used questionnaires show statistically significant differences among the groups, revealing greater handicaps for Group C. Audiometry performed at 4 kHz shows how hearing loss progresses with age, finding differences between men and women. There is a correlation between time-to-treatment in Group C and the cognitive test DSST (−0.26; p = 0.003). Conclusions: HHIE-S, SSQ12, and 4 kHz audiometry are sensitive and feasible tests to implement in screening programs.

Purpose: To describe the anatomic relationship of the lingual nerve with the lateral oropharyngeal structures. Methods: An anatomic dissection of the lateral oropharyngeal wall was conducted in eight sides from four fresh-frozen cadaveric heads. Small titanium clips were placed along the lingual nerve and the most anterior and medial border of the medial pterygoid muscle. Radiological reconstructions were employed for optimal visualization; the coronal view was preferred to resemble the surgical position. The distance between the lingual nerve and the medial pterygoid muscle at its upper and lower portion was measured radiologically. The trajectory angle of the lingual nerve with respect to the pterygomandibular raphe was obtained from the intersection between the vector generated between the clips connecting the upper and lower portion of the medial pterygoid muscle with the vector generated from the lingual nerve clips. Results: The mean distance from the upper portion of the medial pterygoid muscle and superior lingual nerve clips was 10.16 ± 2.18 mm (mean ± standard deviation), and the lower area of the medial pterygoid muscle to the lingual nerve was separated 5.05 ± 1.49 mm. The trajectory angle of the lingual nerve concerning to the vector that describes the upper portion of the most anterior and medial border of the medial pterygoid muscle with its lower part was 43.73º ± 11.29. Conclusions: The lingual nerve runs lateral to the lateral oropharyngeal wall, from superiorly–inferiorly and laterally–medially, and it is closer to it at its lower third.
The main objective of this study is to test the reliability of a non-invasive objective method for the measurement of biomechanical parameters of cervicofacial muscle groups, with the purpose of diagnosis and evaluation of voice disorders' treatments, especially focused on muscle tension dysphonia. Prospective study. The device used is a handheld myotonometer (MyotonPRO) that measures biomechanical and viscoelastic properties in superficial soft tissues frequency, stiffness, elasticity, relaxation time and creep. It is used in the field of medicine, sport and research. This pilot study includes 10 subjects, who have been measured in the masseter, sternocleidomastoid, orbicularis oris, semispinalis capitis, suprahyoid, infrahyoid and trapezius muscles on each side. Measurements were performed by 2 evaluators to assess inter-evaluator reliability. Subsequently, one of them repeated the measurements to assess intra-evaluator reliability. The results revealed good to excellent inter-rater reliability for the masseter, sternocleidomastoid, trapezius and suprahyoid muscles, with lower ICCs for the stiffness and creep properties. Intra-rater reliability was good to excellent for the masseter, sternocleidomastoid, semispinalis capitis and suprahyoid muscles. The lowest ICCs were found in the stiffness and creep properties. The use of a myotonometer to measure the mechanical properties of selected cervical and orofacial muscles is a reliable and reproducible method. Future research is needed to establish an association between the properties of these muscles and their role in voice disorders, as well as to determine whether this tool can aid diagnosis with quantifiable and objectifiable indicators, and for monitoring and treatment efficacy.
